Want to be kind of creepy and very charitable? Kill two birds with one stone by heading over to eBay, right now. Female Mixed Martial Arts fighters — including Ronda Rousey, Felice Herrig, Liz Carmouche and Julie Kedize — are donating signed sports bras for charity, with proceeds going to Keep A Breast. The nonprofit organization is dedicated to eradicating breast cancer for future generations and has received many donations from MMA fighters, including Rosie Sexton‘s top and shorts. As of mid-day Friday, Rousey’s bra (pictured below) has the highest bid. It’s going for $340 (plus shipping).
